Hardware Notice Guide

1. Before linking power supply with the motherboard, please attach DC-in adapter to the motherboard ﬁ rst. Then plug the adapter power to AC outlet. Always shut down the computer normally before you move the system unit or remove the power supply from the motherboard. Please unplug the DC-in adapter ﬁ rst and then unplug the adapter from the AC outlet. Please refer photo 1 as standard procedures.

2. In case of using DIRECT DC-in (without adapter), please check the allowed range for voltage & current of cables. And make sure you have the safety protection for outer issues such as short/broken circuit, overvoltage, surge, lightning strike.

3. In case of using DC-out to an external device, please make sure its voltage and current comply with the motherboard speciﬁ cation.

4. The total power consumption is determined by various conditions (CPU/motherboard type, device, application, etc.). Be cautious to the power cable you use for the system, one with UL standard will be highly recommended.

5. It’s highly possible to burn out the CPU if you change/ modify any parts of the CPU cooler.

6. Please wear wrist strap and attach it to a metal part of the system unit before handling a component. You can also touch an object which is ground connected or attached with metal surface if you don't have wrist strap.

7. Please be careful to handle & don't touch the sharp-pointed components on the bottom of PCBA.

8. Remove or change any components form the motherboard will VOID the warranty of the motherboard.

9. Before you install/remove any components or even make any jumper setting on the motherboard, please make sure to disconnect the power supply ﬁ rst. (follow the aforementioned instruction guide)

10. "POWERON after PWR-Fair” function must be used carefully as below: When the DC power adaptor runs out of power, unplug it from the DC current; Once power returns, plug it back after 5 seconds. If there is a power outage, unplug it from the AC current, once power returns, plug it back after 30 seconds. Otherwise it will cause system locked or made a severe damage.

Remark 1: Always insert/unplug the DC-in horizontally & directly to/from the motherboard. DO NOT twist, it is designed to ﬁ t snugly. Moreover, erratic pull / push action might cause an unpredictable damage to the component & system unit.

handle the 3I770A/CW. Well secure the ALLIGATOR clip of the strap to the end of the shielded wire lead from a grounded object. Please put on and connect the strap before handling the 3I770A/CW for harmlessly discharge any static electricity through the strap.

2. Please use anti-static pad to put any components, parts, or tools on the pad whenever

you work on them outside the computer. You may also use the anti-static bag instead of the pad. Please ask your local supplier for necessary parts on anti-static requirement.

3. Do not plug any connector or set any jumper when the power is on.

2-2 Unpacking checkup

First of all, please follow all necessary steps of section 2-1 to protect 3I770A/CW

from electricity discharge. With reference to section 1-7

please check the delivery package again with following steps:

1. Unpack the 3I770A/CW board and keep all

packing material, manual and driver disc etc, do not dispose !

2. Is there any components lose or drops from the board?

DO NOT CONTINUE TO INSTALL THIS BOARD!

CONTACT THE DEALER YOU PURCHASED

THIS BOARD FROM, IMMEDIATELY.

3. Is there any visible damage on the board?

DO NOT CONTINUE TO INSTALL THIS BOARD!CONTACT

THE DEALER YOU PURCHASED THIS BOARD FROM, IMMEDIATELY.

4. Check your optional parts (i.e. DDR, CF etc.), all necessary jumpers

setting to jumper pin-set, and CMOS setup correctly.

Please also refer to all information of jumper settings in this manual.

5. Check your external devices (i.e. Add-On-Card, Driver Type etc.)

for complete add-in or connection and CMOS setup correctly.

Please also refer to all information of connector connection in this manual.

6. Please keep all necessary manual and driver disc in a good condition for future

re-installation if you change your Operating System.

2-8 Jumper Setting Description

A jumper is ON as a closed circuit with a plastic cap covering two pins. A jumper is OFF

as an open circuit without the plastic cap. Some jumpers have three pins, labeled 1, 2,

and 3. You could connect either pin 1 and 2 or 2 and 3.The below ﬁ gure 2.2 shows the

examples of different jumper settings in this manual.

Figure 2.2

All jumpers already have its default setting with the plastic cap inserted as ON,

or without the plastic cap as OFF. The default setting may be referred in this

manual with a " * " symbol .
